570 Ischemic Colitis Following Endovascular Aortoiliac Aneurysm Repair: A 10-Year Retrospective Review

Kissing Iliac Artery Stent Technique for Salvage of Hypogastric Artery Occlusion Secondary to Iliac Artery Dissection During Endovascular Aneurysm Repair

“…4,5 Ischemic colitis has been reported in up to 1.4% of elective EVAR procedures when preoperative unilateral internal iliac artery embolization is performed. 6 If bilateral hypogastric artery occlusion is required, most investigators recommend staging the embolizations and then delaying the EVAR by 2 to 4 weeks to achieve better outcomes. [7][8][9] However, bilateral hypogastric embolization can still have up to 50% incidence of buttock claudication and impotence.…”

Preservation of pelvic perfusion with iliac branch devices does not decrease ischemic colitis compared with hypogastric embolization in endovascular abdominal aortic aneurysm repair

“…[7][8][9][10] In addition, potentially life-threatening complications such as spinal ischemia and intestinal ischemia can occur at a rate of 0.2% to 0.75% [11][12][13] and 0.5% to 3%, respectively. 7,12,[14][15][16][17] Although ischemic colitis is rare with an incidence of 0.9% in standard infrarenal EVAR and only 2% to 3% during EVAR with hypogastric artery embolization (HAE), 12,14,15,17 it is a highly morbid complication. Approximately 35% of patients with ischemic colitis require surgical intervention, and of those, the mortality rate can be as high as 60%.…”
